Nicole Richie was arrested on charges of driving under the influence early Monday morning, the California Highway Patrol has confirmed to PEOPLE.

She was booked in Glendale and "was cooperative," agent John Balian of the local police force said, adding that her booking sheet showed she is 5'1" and 85 lbs. Her bail was posted at $15,000, and she was released at 7 a.m.

CHP officers responded at about 12:31 a.m. after two 911 callers reported seeing a 2005 black Mercedes SUV going the wrong way on the 134 Highway.

However, a CHP spokesman says, the officers found Richie at a complete stop facing the right direction in the carpool lane in Burbank.

The arrest of the Simple Life star, 24, was first reported by TMZ.com.

A rep for Richie had no comment on the incident.

This isn't Richie's first brush with the law: In February 2003, she was arrested in Malibu and charged with possession of heroin, it was then reported by the Smoking Gun Web site. She was also driving with a suspended license.

She has since been a patient in a drug-rehabilitation hospital and recently was treated for a weight disorder.
